Come on, Your Highness

Emperor Tiangan felt that it was very novel. Looking at Xiao Hong who came to solve the problem two days later, he wondered: "When did Hong'er become so interested in arithmetic?"

"Compared to reading the Four Books and Five Classics, these are much more interesting. Didn't you say that the master will teach them next time? Just think that Xi Chao and I have previewed in advance. Come on, Father. I won't do the rest, it's up to you." Xiao Hong spread the paper on Emperor Tiangan's table.

Emperor Tiangan saw it, well, it was multiplication before, but this time it has become a business division, and the difficulty has increased.

"Why, He Xichao will understand too?"

"Yes, and I am addicted, my son sent someone to send it, and he sent it back the same day. The second uncle has a copy of "Nine Chapters of Arithmetic", and he has a copy of it." Xiao Hong said.

Emperor Tiangan praised: "I can't tell, but that child has a clever mind."

Xiao Hongmoran is not only dexterous, but also a monster, okay?There are still a few papers waiting for you.

"My son has already memorized the formula. The first few questions, you can see if you did it right. I think it's just the other way around." Xiao Hong pointed to the first few simple questions and said, "The multiplication of seven and seven is 49,49 Divided into seven parts, each part should also be seven, right?"

Emperor Tiangan nodded, "That's right."

Xiao Hong, who can correspond to the formula in the formula, has already written the answer, which is almost correct. Emperor Tiangan pointed out a mistake in it, and he can correct it immediately.However, he can't divide two-digit numbers when it exceeds 81. Like the previous 51 fours, the calculation rules related to carry and abdication are a bit complicated. Xiao Hong can't do it without systematic study. Come.

However, He Xichao didn't intend for him to know it now, but just wanted him to understand multiplication and division, so that he won't be clueless when he returns to the palace.

Of course, there is no rush for these things. During the New Year's Eve, when the emperor is free, it is a great opportunity for Xiao Hong to maintain the relationship between father and son. How could He Xichao let him miss it?

What's the meaning of the harem? It's fun to accompany my son to do homework!

It doesn't matter if Xiao Hong can't do it, as long as the emperor can do it.

Those who have learned multiplication and division generally think so, and division is much more difficult than multiplication.

The same is true in this era. The product can be done by paving the floor, but when there is no vertical calculation method, the quotient exceeds the scope of oral calculation, and it is generally done by calculation method or auxiliary abacus.

Abacus needs abacus formulas, which are often used by accountants, so the emperor naturally can’t use them, and it looks unsightly. Counting chips is the only way he can think of. It can be done, but it takes time, and you have to take out hundreds of them. counting.

Xiao Hong looked at Emperor Tiangan's calculations, dismantling them while counting, and asked in surprise: "Is it so troublesome?"

"It's not easy to get rid of business, hey, please be quiet and don't mess with my thoughts."

Emperor Tiangan hasn't played for a long time, his hands are a little rough, and he has to recall the steps, dismantling and calculating the chips all over again, so it really wastes a lot of time.

Although Xiao Hong didn't say anything, he was puzzled, did He Xichao do the same?

"Hong'er, the results are in, come and have a look, Shang Shiba."

"Oh." Xiao Hong immediately wrote down the answer, and then looked down, "Father, there is one last question... It's just that the number is really big. Nine thousand eight hundred and one are divided into 99. ?”

Emperor Tiangan couldn't help frowning when he heard this, and turned around to ask: "Can He Xichao really do it?"

The topic is all from this person, so it is naturally possible.

However, when Xiao Hong saw the counting chips on the table, and thought of the trouble of dismantling and placing them just now, he was not sure, "Probably... my son doesn't know either."

Emperor Tiangan glanced at him, only to see Xiao Hong carefully asked: "Then can you count?"

Of course it can be calculated, but it is quite troublesome, and I guess it is time to go to bed when the calculation is done.

"Then... how about, when my son comes back tomorrow, which empress do you want to go to, can you go?"

It was a good move to use retreat as an advance. Emperor Tiangan looked at him with deep meaning in his eyes.

Xiao Hong scratched his head with a sneer, and whispered: "My son just wants to stay with you for a while..."

Emperor Tiangan calculated one by one, and patiently explained step by step. Although Xiao Hong couldn't understand, he was not annoyed.

"Numbering requires a lot of practice to be accurate and fast. I haven't tried it for a long time, but I'm unfamiliar with it...Okay, let's see, how much is it?"

"Is the top row the merchants?"

"Correct."

"One horizontal and four vertical, five horizontal and one vertical...that's... 99?"

"Yes." Emperor Tiangan put down the calculation in his hand, "It's a pity for He Yu, I remember his knowledge, if not..."

No, you misunderstood, this is all from He Yu's son!Xiao Hong thought silently.

"Okay, let's go back and rest early." Emperor Tiangan touched Xiao Hong's head in a rare way, with a gentle tone.

On the second day, He Xichao received the paper, and the answer was still correct. After the paper, there was a text message, which included the excitement and joy shared by this gentle treated eldest prince.

The emperor, who is so cold at the top, even if he hears the empress and concubines pouring out their love words with shame and timidity, he will only feel that it is because they want him, and the effect will naturally be greatly reduced.

Only a simple child can hit a hit with a casual sentence from the heart.

In other words, whether it is Xiao Hong or Emperor Tiangan, both lack love and cherish the precious time together.

For some reason, He Xichao was a little envious. He missed He Yu a lot. The years with He Yu were the most relaxing and happiest time for him. He was the only father who loved him in his two lifetimes!

But when he saw Xiao Hong's extra question at the end of the letter, he couldn't help but sneered, "Of course it's impossible to use such a complicated method of counting chips. It's exhausting to do the questions like that. Don't worry, I will teach you when I return to the palace." How do you calculate easily."

However, it can be seen from this that Emperor Tiangan's mathematics level is actually not high, and it is far behind Xie Er.

Then... it's interesting.

With the four arithmetic operations, it is natural to use them in practice. Come on, the last paper, Fang Tian walked up.

In the "Nine Chapters of Arithmetic", the chapter on Fangtian is a simple geometric solution. Taking fields of various shapes as examples, find the sides, perimeters, and areas.

Fields of various shapes naturally cover triangles, quadrilaterals, circles, fans, rings, bows...

For future generations, there are special formulas for perimeter and area, which can be solved once you enter it.

In this era, if one studied like Xie Er, he would naturally be able to deduce a similar formula by himself, and put it in front of Emperor Tiangan... it would be beyond the outline.

Emperor Tiangan almost said helplessly: "Why do you need to know these things, Tian Fang has his subordinates to calculate for you."

Xiao Hong asked: "But if I don't understand, how do I know whether the people below me are right or wrong? What if these people fool me?"

Emperor Tiangan laughed and said: "Could it be possible that you, as a prince, went to the field to test it yourself?"

"But I want to know, Royal Father. Anyway, I'm idle. Let's do it. I also want to know a circle. How do I know how big it is?"

Emperor Tiangan vaguely recalled that there was a round rate, but he couldn't remember how much it was.

Xiao Hong had obediently polished the ink for him, and was looking at him with his eyes open.

"Xi Chao said, it's not difficult. He said that the second uncle has written the method. Since Xi Chao's father can do the math, so can my father. The father is much better than the second uncle, isn't it?"

This kind of high hat is very comfortable for Emperor Tiangan to wear on weekdays, but today, when he looked at the several lines on the paper to calculate the area of ​​the round field, the area of ​​the fan, and the final bow shape, he suddenly felt a faint sense of familiar tension.

Thinking back a little bit, it was the kind of pressure that gave Xiao Hong relief from Monet back then.

Similarly, Xiao Hong looked at him with admiration and anticipation, as if he didn't doubt his strength at all.

But the problem is... there is no Du Niang, no brother Gu, and no homework helper. It all depends on one brain, and Emperor Tiangan really can't remember it.

It seems that it's time to ride a tiger again, when Dad's face is on the verge of crumbling.

"Ahem." Emperor Tianqian reached out to take the tea beside him, then frowned slightly.

The tea is cold.

"Your majesty, this old slave will give you another cup."

Eunuch Huang came over with keen eyesight, Emperor Tiangan nodded, but at the moment when the cups were handed over, he casually gave Eunuch Huang a look.

Master and servant have been in the same mind for many years, and Eunuch Huang understood it instantly, and went down with the tea calmly.

After a while, a brand-new pot of high-quality Pu'er was brought to the table. After Huang Gonggong served tea to Emperor Tiangan, he poured another cup for Xiao Hong.

"Although Qingming will come after the Spring Festival, the weather is still very cold. The eldest prince drinks some Pu'er to warm himself up."

The charcoal fire in the house was still burning, but his fingers and toes were still a bit cold. Xiao Hong held the cup and warmed his fingers.

The paper was put aside for the time being, and when Xiao Hong finished his tea, when he remembered, suddenly a little eunuch came in and said, "Your Majesty, the Changqiu Palace has come to report that Concubine Lin has fainted."

Emperor Tiangan suddenly stood up and asked, "When did it happen?"

"Estimated half an hour ago."

"I'll go and have a look, Hong'er, you go back first." Before Xiao Hong could speak, Emperor Tiangan had already left the Long Case, and after two steps, he didn't forget to turn around and say to him, "Put that paper away, and I'll come back tomorrow." Send people to Jing'an Palace."

After finishing speaking, the person left the main hall of the Qing Dynasty, seeming very anxious.

Xiao Hong stared blankly at the wide-open palace door, and stopped Eunuch Huang, "It's just a concubine, why is the father in such a hurry, is he very favored, why do you want to see it in person?"

"Yes, yes..." What is it, how many times can the emperor go there a year.

Eunuch Huang shook his head and followed.

As soon as he went out, a guard asked in a low voice: "Eunuch Huang, this urgent report..."

Eunuch Huang looked back and found that Xiao Hong hadn't followed, so he quickly said, "Keep it for next time."

Emperor Tiangan has come out, even the imperial chariot is ready, it is too deliberate to say not to go now.

I had no choice but to go to the harem and take a trip to the Changqiu Palace to be concerned.

Concubine Lin was overjoyed that her illness was cured.

"As soon as the concubine's hands and feet get cold in winter, the imperial doctor said that the qi and blood deficiency after the miscarriage caused fainting, and it will take some time to mend it. I will take care of it. Thank you for your concern. The emperor can come. I really didn't expect it. It's really too much." Pleased, Your Majesty..."

Concubine Lin, a little bird, clings to her, complaining about the pain of lovesickness.

Emperor Tiangan still remembered the paper in the Qingzheng Hall, bit the bullet and perfunctory a few times, rewarded him with a bunch of good medicine, told him to rest more, and left.

It took less than a quarter of an hour from sitting down to standing up, but even so, Changqiu Palace still attracted a lot of red eyes from the harem.

As soon as the front of the head fainted, the emperor came on the back foot, didn't he really care about what?

I can't tell it normally, but I didn't expect to be so favored. Could it be that Concubine Lin is the emperor's heart?

All kinds of speculations arose, and there was another disturbance in the harem. No one knew that this was just an excuse.

Emperor Tiangan sat at the table, drinking tea while staring at the paper.

Seeing his worried look, Eunuch Huang asked, "If the old slave goes out and asks, who would be more proficient in learning?"

Emperor Tiangan glanced at him angrily, "Who can you ask, the one who watches the small gate or the gate? Or a slave like you?"

Now during the Spring Festival, all the officials are still on vacation at home, the cabinet is empty, and the guards of the imperial army, the imperial physician, and the various departments of the Ministry of Internal Affairs are on duty.Of course, the maids and servants are also there, but all of these people are estimated to be inferior to Emperor Tiangan himself.

Eunuch Huang found himself in a difficult situation, "This...what should I do?"

"This kid Hong'er has different hobbies from others, and he always thinks about strange things." Emperor Tiangan couldn't help complaining.

Ordinary people's hobbies are nothing more than elegant things such as poetry, poetry, piano, chess, calligraphy and painting, but Emperor Tiangan doesn't understand, and he can communicate a little bit after reading and listening a lot.

And what about Xiao Hong?Playing with a toy requires cleverness, and asking questions requires brains. Emperor Tiangan thinks that this son is really loved and hated, and he really wants to grab him and spank his ass hard.

Eunuch Huang glanced carefully at Emperor Tiangan's face. Although he was a little annoyed, he was not angry. He actually appreciated it when he looked carefully.

So he said: "The eldest prince's mind is quick, his mind is flexible, and he has the energy to study, but no one in the palace can accompany him. He Bandu went back to the mansion again, so he can only come to the emperor, because he is close to the emperor."

Needless to say, Emperor Tiangan also felt that Xiao Hong was becoming more and more unrestrained in front of him, and he dared to speak up when he had something in his heart. Although he was a bit presumptuous, his true temperament was rare in the palace.

Emperor Tiangan likes Xiao Hong like this, so he subconsciously encourages and protects the precious intimacy and tacit understanding between father and son.

"I don't know how long Hong'er can keep like this, royal family, it's always rare." He sighed.

Eunuch Huang was silent. He grew up with Emperor Tiangan. At that time, there was no father, son and brother talking about Duodi. They were kind on the surface, and they were ruthless behind the scenes. In front of the powerful, these were all jokes.

"Send someone to Xie's house. I heard Mr. Xie once said that the third child of his grandchildren didn't want to take the imperial examination, so he wanted to travel around. I don’t know, presumably the second brother Xie should know how to solve it, right?”

Eunuch Huang said: "Yes."

Xie Er was summoned out of the study for no reason, and then a piece of paper was handed to him, and a father-in-law wearing a felt hat who had not taken off his cloak smiled and said to him: "The emperor heard that Mr. Xie is good at arithmetic." , Coincidentally, please ask Master Xie for your help with the questions in this paper, the old man is in a hurry, so you should do it now, and when you are done, you can present it to the emperor."

Mr. Xie Ge is also there, it’s the New Year’s Eve, the palace braves the cold night to rush over, thinking that there is something important to discuss with the emperor, even the official uniform and carriage are prepared, unexpectedly...

No matter how well cultivated Xie Ge was, he couldn't come back to his senses for a while, so he could only sigh: "Then let's do it now."

Xie Er held the paper, his brows suddenly frowned, his expression was a bit puzzled, so he said to the attendant in the Qingzheng Hall: "Dare to ask Eunuch, who is the person who wrote the question?"

The servant thought for a while and said: "The eldest prince has recently become obsessed with arithmetic, and the emperor thought of Mr. Xie. I wonder if you can explain it?"

Eldest Prince, Old Xie Ge frowned slightly.

Xie Er nodded, "It can be solved, it's not difficult."

The servant heard the words and breathed a sigh of relief, "That's really great, please go ahead, and the emperor asked you to write down the solution as well."

"Yes."

It's just simple geometry, as long as you know the method, you will have the answer soon.

It’s just that I still need to write the solution. Xie Er doesn’t know the level of the first prince, but I heard that he is not very old, so he must write in more detail, so he drew pictures and marked them, and wrote down the process and principle of each question Finished, wasted a lot of time.

The servant got the paper and solution, put it away carefully, then cupped his hands, and left in a hurry.

Xie Ge then asked, "Is there a problem with that paper?"

Xie Er said: "It's from Xi Chao, the notes are the same."

Old Xie Ge thought deeply, "He gave the eldest prince a question, and the eldest prince asked the emperor to solve it. Why?"

Xie Er looked at his grandfather and said, "You don't even understand, and grandson doesn't understand. If there is nothing wrong, grandson will leave first."

Xie Ge always thinks more than others, but because of his rich life experience, he can't figure it out, this is just an excuse He Xichao gave Xiao Hong to exchange feelings with Emperor Tiangan, it has no other meaning.

The author has something to say: He Xichao: Some things adults think are too complicated, spread your hands

Yao: ...you have the nerve to talk about others?
